Sewer inspections play a critical role in maintaining the safety, functionality, and long-term reliability of residential plumbing systems. These inspections help identify hidden issues such as blockages, cracks, root intrusion, misaligned joints, and deteriorated pipe materials—problems that can lead to major damage and costly repairs if left undetected.
By performing routine sewer camera inspections, homeowners can protect their property, avoid emergencies, and make informed maintenance decisions. For homebuyers, a sewer inspection provides essential insight into one of the most expensive underground systems on the property.
What Is a Sewer Inspection?
A sewer inspection is a non-invasive evaluation of a home’s drain and sewer lateral using a high-definition camera mounted on a flexible cable. The camera is inserted through a cleanout or access point and navigated through the sewer line while transmitting live video to a monitor.
This allows the inspector to visually assess:
- Pipe condition and material
- Cracks, corrosion, and deterioration
- Root intrusion
- Offsets, bellies, and structural defects
- Blockages and buildup
Video inspections are the only practical way to examine underground sewer lines without excavation.
Why Sewer Inspections Are So Important
Preventing Costly Damage
Undetected sewer problems can lead to:
- Sewage backups into the home
- Foundation and structural damage
- Contaminated soil and groundwater
- Expensive emergency repairs or full replacements
Early detection allows for targeted repairs before small defects become major failures.
Protecting Health & Safety
Damaged sewer lines can release harmful bacteria, viruses, and gases such as:
- E. coli
- Salmonella
- Hepatitis A
- Methane and hydrogen sulfide
Inspections help prevent environmental contamination and indoor air quality issues.
